The pineapple shows the fibonacci sequence as they possess the fibonacci spirals and also have the fibonacci sequence shown in the number of sections there are. The involute of a circle looks like an Archimedean, but is not: see InvoluteExamples. The Fibonacci Spiral consists of a sequence of circle arcs. Spirals which do not fit into this scheme of the first 5 examples: A Cornu spiral has two asymptotic points. Could this relate to the Fibonacci spiral which grows you could even say it somewhat swells. Approximations of this are found in nature. There are 8 spirals in one direction, 13 spirals in the opposite direction, and 21 spirals vertically. Fibonacci numbers determine the number of spirals that appear on the fruit’s skin. Their growth is determined by the Fibonacci sequence in several ways. Pine comes from the root *peie meaning “to be fat, swell”. What makes the Fibonacci sequence so interesting is that you will discover the numbers of the sequence all over nature. Pineapples are mathematical objects found in nature. It’s also in many plants and therefore fruit such as pinecones and pineapples. A Fibonacci prime is a Fibonacci number that is prime, a type of integer sequence prime. But maybe these aren’t exceptions but instead they have their own rules… ), but before long, you'll find yourself adding. This isn’t easy to do on many plants (evident below) and it may not be possible on certain ones. Often referred to as the natural numbering system of the cosmos, the Fibonacci sequence starts out simply (0+1 1, 1+1 2, 1+2 3, 2+3 5, 3+5 8. If you take a look at the nearest plant to you, how many leaves does it have? When you count them in spirals they may begin to reflect the Fibonacci sequence and spiral. The golden ratio () is present in the angles between each leaf so it perfectly separates them to prevent as much overlap as possible. Like the staggered pattern of certain plants’ leaves to optimise the absorption of sunlight so it hits every leaf. It is surprisingly in so many things around us. The Fibonacci sequence is extraordinarily interesting.
